how to use a different domain/subdomain for authors/catagories on single site?

wp-config.php if ( is_alt_domain( $_SERVER[‘SERVER_NAME’] ) ) { $domain = str_replace( ‘www.’, ”, $_SERVER[‘SERVER_NAME’] ); define( ‘WP_SITEURL’, ‘http://www.’ . $domain ); define( ‘WP_HOME’, ‘http://www.’ . $domain ); } else if (is_sub_domain( $_SERVER[‘HTTP_HOST’] ) ) { $domain = “{$_SERVER[‘HTTP_HOST’]}”; define( ‘WP_SITEURL’, ‘http://’ . $domain ); define( ‘WP_HOME’, ‘http://’ . $domain ); } else if (!

How can I select a primary category?

There is no concept of “primary” term in WordPress. Taxonomies are grouping mechanism. Post belongs to multiple terms on equal terms (no pun intended). No term is “more” of a group than the rest. From brief description of your use case, intuitively Artists would be much better defined as CPT too. But then it comes … Read more

Elegant way to add parent categories?

wp_set_post_terms() uses wp_set_object_terms(). There is an action hook called set_object_terms which fires on successful setting of an object’s terms. The action hook looks like this do_action ( ‘set_object_terms’, int $object_id, array $terms, array $tt_ids, string $taxonomy, bool $append, array $old_tt_ids ) What we can do here is, inside our action callback function, we can check … Read more

Use tag interface for hierarchical taxonomy?

Here’s how I did it. Just add a conditional that checks if the page being loaded is an admin page or not. If it is an admin page, set hierarchical to false, otherwise set hierarchical to true. Like so: $args = array( ‘hierarchical’ => true, ‘labels’ => $labels, ‘show_ui’ => true, ‘query_var’ => true, ‘rewrite’ … Read more

How do I create a way for users to assign categories to a post from the frontend?

Add forward slash on categories url (serve one version of a url)

Filter category_link so WordPress creates slashed URLs for categories, and redirect_canonical so it accepts those URLs: add_filter( ‘category_link’, ‘wpse_71666_trailingslash_cat_url’ ); add_filter( ‘redirect_canonical’, ‘wpse_71666_trailingslash_cat_url’, 20, 2 ); function wpse_71666_trailingslash_cat_url( $url, $request=”” ) { if ( ‘category_link’ === current_filter() ) return rtrim( $url, “https://wordpress.stackexchange.com/” ) . “https://wordpress.stackexchange.com/”; if ( “$url/” === $request and is_category() ) return $request; … Read more

Woocommerce product categories order [closed]

Woocommerce stores ‘order’ metakeys in the table wp_woocommerce_termmeta. The mechanism it uses is the same as menu_order for posts. Something like this should work: $terms = get_terms(‘product_cat’); //sort $terms somehow $i = -1; foreach ($terms as $term) { $i++; update_woocommerce_term_meta( $term->id, ‘order’, $i); } The same procedure can be used to sort other Woocommerce taxonomies … Read more

Exclude categories from Loop, queries, widgets, post navigation

Excluding categories with pre_get_posts() I found that excluding a category via pre_get_posts() and set_query_var() would work fine except for widgets. The Recent Post Widget would only exclude the category when using $query->set() instead. <?php /** * Does NOT apply to the Recent Posts widget. */ function glck1403271109_exclude_categories( $query ) { $excluded = array( ‘1’, ‘2’ … Read more

How to tax query X number of posts related by tag first, then by category if not enough in tag-related

You cannot do this in one query, this is a bit too advanced for what WP_Query can do at this point in time. We will need to run at least two (I’m going to use 3) queries here to achieve what you want FIRST QUERY The first query will query for posts according to post_tag, … Read more

Default WP Gallery – show only galleries of a certain category

What I suspect is that those Gallery Categories are not the category taxonomy. They are probably a registered taxonomy, registered by the same script which added the gallery post type. To find out, click on the Gallery Categories ( in the provided image ) and you will be redirected to a URL such as this: … Read more
